~I <br />6.7 Moisture Control <br />6.7.1 General <br />During compaction operations, the materials being <br />placed and the surface of the fill shall be maintained <br />within the moisture content range required to permit <br />proper compaction to the specified densit}~ with the <br />' equipment being used. The moisture content cf the fill <br />materials prior to and during compaction shall be uniform <br />throughout each layer of the material. <br />If material spread on the fill is crier than <br />specified for compaction, the Contractor shall spray <br />water on each layer of the fill and work the moisture <br />into the fill by harrowing or other approved means until <br />a uniform distribution of moisture at the proper content <br />is obtained. Material spread on the fill that is too wet <br />for proper compaction shall be removed or it may be left <br />on the fill and permitted to dry, assisted by discing and <br />1 harrowing as necessary, until the moisture ~:ontent is <br />reduced to an amount suitable for obtaining the specified <br />' percent of compaction. If material is left on the fill to <br />dry, no material may be placed over the we: material <br />' until it has been dried, reworked, and properly <br />compacted. <br />' Mixing of wet and dry material on the fill to obtain <br /> the proper moisture content shall not be done. Placing <br /> mixed material on the fill shall be done after the <br /> material has cured and a uniform distribution of the <br /> moisture content has been achieved and approved by the <br /> Engineer. <br /> <br /> <br /> N- 15 <br />
